Publication date: 2026-09-08

Last updated on: 2026-09-15

Assigner: Android (associated with Google Inc. or Open Handset Alliance)

Description

In p2p_process_prov_disc_bootstrap_req of p2p_pd.c, there is a possible out of bounds write due to a heap buffer overflow. This could lead to remote (proximal/adjacent) code execution with no additional execution privileges needed. User interaction is not needed for exploitation.

CWE

KEV

CWE ID	Description
CWE-787	The product writes data past the end, or before the beginning, of the intended buffer.
CWE-122	A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Attack-Flow Graph

Executive Summary

This vulnerability is a heap buffer overflow in the p2p_process_prov_disc_bootstrap_req function of p2p_pd.c. It allows an out of bounds write, which could lead to remote code execution in nearby devices without needing extra privileges or user interaction.

Impact Analysis

If exploited, this vulnerability could allow attackers within proximity to execute arbitrary code on affected devices. This might lead to unauthorized access, data theft, or further compromise of the device and connected systems.

Mitigation Strategies

Apply the latest security patches from the Android vendor immediately to address the heap buffer overflow in p2p_process_prov_disc_bootstrap_req. Disable Wi-Fi Direct or P2P features if not in use until patched.
